2013 Dinan S3 BMW 550i

Steve Dinan has been enhancing BMW models since 1979. But don't throw his company into the ring with the dozen or so other tuners who tweak, tinker and piggyback upgrades on the famed German marque. Dinan is a tuner, but it's also an engineering firm that writes its own software, builds its own parts and then backs everything it does with a factory-grade warranty. That sort of fastidiousness comes at a price, but most of its customers - including the powerhouse of BMW Motorsport - rely on Dinan to help them come out on top.
In stock form, BMW's 550i is a formidable four-door with a twin-turbocharged 4.4-liter V8 rated at 400 horsepower and 450 pound-feet of torque. While those figures allow it to run with quick company (0-60 in 5.0 seconds, according to the automaker), Dinan puts the sedan's kettle on full boil with its S3 package. Starting with the engine, the performance engineering firm bolts on larger turbochargers, air-to-water intercoolers, a trick strut tower brace cold air intake, a quad-pipe free flow exhaust and its own engine management software. Pump in some premium fuel, and the result is 542 horsepower and 587 pound-feet of torque. Power is sent through the stock eight-speed automatic to a limited slip rear differential (Dinan will upgrade xDrive all-wheel drive models, too).
The Dinan S3 also features and extensive suspension upgrade that includes new front camber arms and low compliance rear control arms (engineered to reduce understeer and improve turn-in). The stock dampers are retained, but new bump stops are installed along with new springs. Overall, the car rides about a half-inch lower than stock to improve roll rate. To reduce unsprung weight, forged 20-inch HRE Performance wheels are fitted at all four corners (wearing Michelin Pilot Super Sport tires - 275/35ZR20 up front and 295/35ZR20 in the rear). Lastly, the company remaps the factory Electronic Damper Control (EDC) software with its own Dinan Shockware to work in conjunction with the new enhancements.

This Or That: 1980 Oldsmobile 442 vs. 1989 BMW 635CSi [w/poll]

The last time I roped a coworker into an automotive debate, I lost. Resoundingly, I might add. Still, 2,385 voters chose to cast their lots for the Fiat 500 Abarth, as opposed to 5,273 choosing the Ford Fiesta ST, and so I can rest easy in the knowledge that at least 30 percent of you, dear readers, see things my way. I still like to think we have more fun, too.
My loss in the first round of our This or That series, in which two Autoblog editors pick sides on any given topic and then attempt to explain why the other is completely wrong, didn't stop me from picking another good-natured fight, this time with Senior Editor Seyth Miersma. Last time, our chosen sides were eerily similar in design, albeit quite different in actual execution. This time, our vehicular peculiarities couldn't seemingly fall any further from one another: A 1980 Oldsmobile 442 wouldn't seem to match up in comparison to a 1989 BMW 635CSi.
How did we come up with such disparate contenders? Simple, really. Seyth and I mutually agreed to choose a car that's currently for sale online. It had to be built and sold in the 1980s, and it had to be a coupe. The price cap was set at $10,000. The fruits of our searching labors will henceforth be disputed, with Seyth on the side of the Germans, and myself arguing in favor of the Rocket Olds. Am I setting myself up for another lopsided loss?

BMW pondering hardcore M4 to celebrate 100 years?

2013 is the year for Lamborghini, Aston Martin and the Porsche 911, but 2016 will be the year for BMW. That's when the Munich-based maker of the Ultimate Driving Machine will celebrate its 100th birthday, with what will probably be a year-long celebration. Part of that 365-day party will, reportedly, be an even hotter version of the new BMW M4, which is set to debut in January at the Detroit Auto Show.
Yes, according to Australia's Car Sales, the über-M4 has been hinted at by higher-ups at BMW's M division, who claim the rear seats will be removed, much like the M3 GTS, while other weight-saving measures will be used to try and bring the M4's weight below 3,000 pounds. There's no mention of engine mods, but if the M4's biturbocharged six is as good as we think it'll be, that's not a deal-breaker for us.
The lightening process on the so-called M4 GTS would involve replacing the hood and front fenders with parts made of carbon fiber, while the doors would switch from steel to aluminum. Besides the deletion of the rear seats, Car Sales is predicting lightweight racing buckets, with a carbon-fiber shell and a minimal amount of padding. Expect lots and lots of Alcantara, in place of leather.
